Public Notice

This webpage’s purpose is to bring awareness to the City’s ability to provide floodplain information on your property. As a public outreach effort, the page contains many useful tips regarding flood insurance, flood safety, floodplain protection, and flood damage mitigation.

Peachtree Corners is bordered by the Chattahoochee river to the north. This is the main water body and most tributaries and streams in Peachtree Corners lead to this primary water source. As a result, flooding damage can occur when streams are inhibited, and water cannot reach the river.

Is My Property in a Floodplain?

A floodplain is a flat area of land adjacent to a river that can experience flooding.

It is important for residents to find out if their property falls in an area where flooding is a hazard. If you want to know if a property is in the Special Flood Hazard Area, view the City of Peachtree Corners Floodplain Map and type in your address to find your property on the map. The city can provide information about flood hazards, flood insurance ratings, and natural floodplain functions of areas that should be protected.

For questions pertaining to the floodplain, email the City’s Certified Floodplain Manager, Katherine Francesconi at

Flood Insurance

Property owners within floodplains are advised to have flood insurance. If you don’t have flood insurance and are interested in getting coverage, please speak with your insurance agent.

  Read about mandatory floodplain insurance

Please visit  for information on where and why to buy flood insurance. Flood damage isn’t covered by standard homeowners’ insurance policies, and just one inch of floodwater can cause more than $25,000 in damage.

Peachtree Corners is a participant in the National Flood Insurance Program (NFIP) which is backed by the Federal government and is available to everyone, even for properties that have been flooded. Buy an NFIP policy from your insurance company. Even if your home is in a low- or moderate-risk flood zone, FEMA recommends purchasing insurance from NFIP. More than 25 percent of flood insurance claims come from properties that are not in identified high-risk zones. Flood insurance covers all surface floods.
